Fuel Injector: Technician Safety Information

Lower O-Ring Removal Caution

Caution:  Verify that the lower (small) O-ring of each injector does not remain in the lower manifold in order to reduce the risk of fire and personal
injury.

If the O-ring is not removed with the injector, the replacement injector with new O-rings will not seat properly in the injector socket. Improper seating
could cause a fuel leak.
